Police in Escondido and San Diego said they continue to work together and search for the gunman, a cop impersonator who police said shot Stewart, 57, during a daylong crime spree in the two cities.

Authorities said they believe the same man was responsible for a Monday morning robbery at gunpoint in Mission Valley, followed a few hours later with the Escondido shooting and then an afternoon carjacking at gunpoint in southeastern San Diego.

At the carjacking, he had a female accomplice. They both wore vests that said “police.”

Police described the gunman as Latino, 30 to 40 years old, 5 feet 7 inches tall with a stocky build. He was unshaven and wore a black, long-sleeved shirt, black pants and a black windbreaker-type jacket.

The woman was described as a Latina with a slim build and dressed in black and wearing a ski mask.

During the carjacking, both wore vests that said “police” in white letters.
